[0019]
FIG. 1 is a block diagram illustrating a control system. Reference numeral 26 denotes a first random number generating means which repeatedly generates a random number value for a specific display mode determination for determining whether or not the display mode of the stopped symbol after the change of the first symbol display unit 13 is a predetermined mode. For example, when the probability that the stopped symbol after the change of the first symbol display means 13 becomes the predetermined mode is 1/350, random numbers from 0 to 349 are sequentially generated.
[0020]
Reference numeral 27 denotes a first display mode determination unit, which randomly selects a random number value generated by the first random number generation unit 26 on condition that the first symbol starting unit 14 detects a game ball, and determines that the random number value is a predetermined mode random number value. When the random number value is a non-predetermined mode random value, it is determined to be the non-predetermined mode. In this embodiment, of the random numbers 0 to 349, the random number “7” is set as the predetermined mode determination random value, and when the random number random determination is “7”, the first display mode determination unit 27 The mode is determined.
[0021]
Reference numeral 28 denotes first symbol variation control means, which changes the first symbol of the first symbol display means 13 for a predetermined time on condition that the first symbol starting means 14 detects a game ball, and displays the first display mode at that time. The first symbol of the first symbol display means 13 is variably controlled so that the stopped symbol after the variation of the first symbol display means 13 displays either a predetermined mode or a non-predetermined mode according to the determination result of the determination means 27. It has become.
[0022]
29 is a profit state generating means, which is advantageous to the player by converting the variable winning means 15 from the closed state to the open state on condition that the stopped symbol after the change of the first symbol display means 13 is in a predetermined mode. It is for generating a gaming state. That is, the profit state generating unit 29 opens the opening / closing plate 23 to the front side when the first symbol stops displaying the predetermined mode, and when a predetermined time (for example, 30 seconds) has elapsed from the opening, or before the predetermined time has elapsed. Has a control function of controlling the opening and closing of the variable winning means 15 so that the opening and closing plate 23 closes when a predetermined number (for example, 10) of gaming balls have won the winning opening 22. By opening the variable winning means 15, It is configured to generate a profit state advantageous to the player.
[0023]
Numeral 30 denotes a second random number generating means for repeatedly generating a random number value for determining a special display mode for determining whether or not to change the display mode of the stopped symbol after the change of the second symbol display means 16 to a special mode. For example, when the probability that the stopped symbol after the change of the second symbol display means 16 becomes the special mode is 2/10, random numbers from 0 to 9 are sequentially generated.
[0024]
Reference numeral 31 denotes a second display mode determination unit, which randomly selects a generated random number value of the second random number generation unit 30 on condition that the specific area 24 detects a game ball. When the random number value is a non-special random number value, the non-special mode is determined.
[0025]
In this embodiment, among the random numbers 0 to 9, the random numbers “3” and “7” are set as special mode determination random numbers, and when the random number is “3” or “7”, The second display mode determining means 31 determines that the display mode is the special mode.
[0026]
Reference numeral 32 denotes a second symbol change control unit which changes the second symbol of the second symbol display unit 16 for a predetermined time on condition that the specific area 24 detects a game ball, and a second display mode determination unit 31 at that time. According to the determination result, the second symbol of the second symbol display means 16 is controlled to change so that the stopped symbol after the variation of the second symbol display means 16 displays either the special mode or the non-special mode. ing.
[0027]
In this embodiment, for the sake of explanation, under the control of the second symbol variation control means 32, the stopped symbol after the variation of the second symbol display means 16 displays the same numeric symbol as the lottery random number value.
[0028]
Reference numeral 33 denotes a profit state regenerating means, which instructs the profit state generating means 29 to regenerate a profit state on condition that the stopped symbol after the change of the second symbol display means 16 is in a special mode, and sets a predetermined mode. The profit state is generated again after the profit state generated due to the termination.
[0029]
Note that the profit state regenerating unit 33 determines whether the second display mode determination unit 31 determines the special mode, or the stop symbol after the change of the second symbol display unit 16 becomes the special mode. In the above, the profit state generating means 29 may be instructed to regenerate the profit state, and it is sufficient that the profit state is generated again after the profit state ends.
[0030]
Reference numeral 34 denotes a notification control means for generating a predetermined sound effect from the speaker 7 when the profit state is generated by the profit state generating means 29, when the profit state is regenerated by an instruction of the profit state regenerating means 33, and the like. The game state display lamp 35 emits light, blinks, and emits light to notify the player of the game state at that time.
[0031]
Next, the operation of the above-mentioned ball game machine will be described. When the firing handle 10 of the firing means 9 is operated in a state where the game balls are on the upper plate 6, the game balls of the upper plate 6 are supplied to the firing unit one by one in conjunction with the firing operation of the firing means 9, and the game balls are supplied one by one. Is hit with a hammer, and is sequentially fired along the guide rail 11 toward the game board 3.
[0032]
The game ball fired on the upper side of the game board 3 falls into the normal prize means 17a, 17b or the like while falling along the board surface of the game board 3, or falls without winning and falls from the out port. It is guided to the back side.
[0033]
When the first symbol starting means 14 detects the passing or winning of the game ball, the first symbol of the first symbol display means 13 starts symbol variation by the first symbol variation control means 28, and the first display mode determination means 27. Selects the random number value generated from the first random number generating means 26 when the first symbol starting means 14 detects a game ball, and displays the stopped symbol after the fluctuation of the first symbol display means 13 from the random number value. It is determined whether the mode is the predetermined mode or the non-predetermined mode.
[0034]
When the first display mode determination unit 27 determines that the first mode is the predetermined mode, after the first symbol of the first symbol display unit 13 fluctuates for a predetermined time, all the symbols are the same, for example, “7 / 7.7”. When it is determined to be a non-predetermined mode that is a combination of the symbols, the vehicle stops in a non-predetermined mode in which at least one symbol is different, such as “7.6.7”.
[0035]
When the first display mode determination unit 27 determines that the symbol is the predetermined mode, and the stopped symbol after the change of the first symbol display unit 13 becomes a predetermined mode such as “7.77.7”, the profit state generation unit 29 operates. The opening / closing plate 23 of the variable winning means 15 is opened to the front side, and a large number of game balls are guided by the opening / closing plate 23 to easily win the winning opening 22. As a result, a profit state in the first round advantageous to the player is generated, and the player can enjoy a great return of profit.
[0036]
The open / close plate 23 of the variable winning means 15 closes when a predetermined time has elapsed or when a predetermined number of game balls have been won, thereby ending the profit state in the first round.
[0037]
However, when the game ball won while the variable winning means 15 is open wins or passes through the specific area 24 and the specific area 24 detects a game ball, the second symbol display is controlled by the second symbol variation control means 32. The second symbol of the means 16 starts symbol variation. At the same time, the second display mode determination means 31 randomly selects a random number value generated from the second random number generation means 30 when the game ball in the specific area 24 is detected, and after the second symbol display means 16 fluctuates from the random number value. It is determined whether the display pattern of the stop symbol is the special mode or the non-special mode.
[0038]
When the second display mode determination unit 31 determines that the second mode is the special mode, the second symbol of the second symbol display unit 16 fluctuates for a predetermined time, and then stops in the special mode of “3” or “7”. When it is determined to be the special mode, the operation is stopped in a non-special mode other than “3” and “7”.
[0039]
When the second display mode determination unit 31 determines that the symbol is the special mode, and the stopped symbol after the change of the second symbol display unit 16 becomes the special mode of “3” or “7”, the profit state regenerating unit 33 changes the profit state to the profit state. Since the regenerating of the profit state is instructed to the generating means 29, the profit state of the second round is generated by the control of the profit state generating means 29 after the profit state at that time ends. Therefore, the opening / closing plate 23 of the variable winning means 15 is once closed and then opened again, so that the player can receive a great profit again.
[0040]
When the second display mode determining means 31 determines that the symbol is the non-special mode, the stop symbol is stopped in a non-special mode other than "3" and "7", and the profit state does not reoccur.
[0041]
When the profit state of the first round is generated or the profit state of the second round or later is generated again, a predetermined sound effect is generated from the speaker 7 and the game The state display lamp 35 emits light or blinks to notify the player of the game state at that time.
[0042]
As described above, when the stop symbol after the change of the first symbol display means 13 is in a predetermined mode, and the profit state of the first round is generated by the profit state generating means 29, thereafter, the profit state of the next round for each round. Is determined by lottery and the profit state of the next round is generated after the profit state of the round ends, so that the playability after the occurrence of the profit state is improved and the interest of the player is improved. Can be increased.
[0043]
In particular, the second symbol of the second symbol display means 16 is changed on condition that the specific area 24 detects a game ball which has won the variable winning means 15, and a condition that the stopped symbol after the change becomes a special mode. By generating a profit state in the next round, it is an object of interest whether or not the stopped symbol after the change of the second symbol display means 16 becomes a special mode, thereby further improving the interest of the player. .
[0044]
Moreover, the random number value of the first random number generating means 26 is randomly selected on condition that the specific area 24 detects the game ball, and whether the first display mode determining means 27 is in the predetermined mode or the non-predetermined mode is determined based on the random number value. In accordance with the determination result, the display pattern of the stop symbol of the second symbol display means 16 is controlled according to the determination result, and the random number value of the second random number generation means 30 is randomly selected on condition that the specific area 24 detects a game ball. The second display mode determination means 31 determines whether the display mode is the special mode or the non-special mode based on the random number, and controls the display mode of the stop symbol of the second symbol display means 16 according to the determination result. After the first symbol display means 13 and the second symbol display means 16 change, a predetermined mode and a special mode can be generated with a predetermined probability.
[0045]
In addition, since the second symbol display means 16 is provided integrally with the variable prize means 15, the variable prize means 15 and the second symbol display means 16 can be centrally arranged on the game board 3, and the structure can be simplified, Further, both can be easily attached to the game board 3.
[0046]
In this embodiment, the specific area 24 detects a game ball that has won the variable winning means 15 in each round, and as long as the stop symbol after the change of the second symbol display means 16 is in the special mode, the next round. The profit status is to be generated continuously. However, if the profit state is continuously generated for a predetermined number of rounds, the function of the profit state regenerating means 33 may be temporarily stopped at that time. That is, the profit state regenerating means 33 may limit the number of reoccurrence of the profit state to a predetermined number (for example, 15). In this case, by appropriately setting the number of rounds, the player does not receive excessive profit.
[0047]
FIG. 4 exemplifies a second embodiment of the present invention, in which a plurality of types of predetermined modes in which the first symbol display means 13 is stopped and displayed after the variation are set, The probability that the stopped symbol after the change of the second symbol display means 16 becomes the special aspect changes with respect to the second display aspect determination means 31 on condition that the particular symbol becomes a specific aspect among the predetermined modes of the type. A probability control means 37 is provided, and when the probability control means 37 is functioning, the fact that it is functioning is notified to the player by the speaker 7 and the game state display lamp 35.
[0048]
In this embodiment, for example, ten types from "0.0.0" to "9.9.9" are set in the predetermined mode of the first symbol display means 13. Then, the probability control means 37 determines that the stop symbol after the change of the first symbol display means 13 is a part of the ten kinds of predetermined modes, that is, "1.1.1", "7 / 7.7" or the like. In the case of the specific mode by the combination of the odd symbols, a command of the probability variation is issued to the second display mode determination means 31, and the probability that the stopped symbol after the variation becomes the special mode is calculated from 2/10 of the normal probability. The probability is changed to a high probability of 6/10 to 9/10, and when the profit state regenerating means 33 does not issue a re-generation command even if a profit state occurs, the probability is returned from the high probability to the normal probability. It has become.
[0049]
In this embodiment, if the stopped symbol after the change of the first symbol display means 13 becomes a predetermined mode of an even symbol or an odd symbol, a profit state is generated by the profit state generation means 29 and the variable winning means 15 is opened. On the other hand, when the predetermined mode is an odd symbol, the probability control unit 37 operates, and the probability that the stopped symbol after the change of the second symbol display unit 16 becomes the special mode varies from the normal probability to the high probability state.
[0050]
Then, when the specific area 24 detects a game ball that has won the variable prize means 15 while the profit state is occurring, the second symbol display means 16 starts symbol fluctuation, and the second display mode determination means 31 outputs the second random number. The random number value of the generating means 30 is randomly selected, and it is determined whether or not the changed stop symbol of the second symbol display means 16 is a special mode.
[0051]
Since the probability of occurrence of the special mode at this time fluctuates from the normal probability to the high probability state, the probability that the stopped symbol after the change of the second symbol display means 16 becomes the special mode is large, which is relatively easy. The next round of profit status occurs. Therefore, the player can easily enjoy the profit by the continuous occurrence of the profit state, and the interest of the player is improved.
[0052]
If the probability is changed to a high probability by the probability control means 37, a predetermined sound effect is generated from the speaker 7 by the notification control means 34, and the gaming state display lamp 35 flashes and emits light at a predetermined cycle, so that the player is notified to the player. To notify that the state is high probability. Therefore, the player can easily grasp that the occurrence probability of the specific state at that time is the high probability state.
[0053]
The high probability state by the probability control means 37 continues as long as the reoccurrence of the profit state continues. However, if the specific area 24 does not detect a game ball that has won while the variable winning means 15 is being opened, the probability control means 37 The control returns from the high probability to the normal probability, and thereafter the game proceeds with the normal probability.
[0054]
In this embodiment, the stop symbol after the change of the first symbol display unit 13 is in a specific mode of the odd symbol, and the probability control unit 37 starts the round when the profit status is generated by the profit status generation unit 29. By working, the probability of the special mode being changed after the second symbol display means 16 changes is set to the high probability state. However, the probability may be changed to the high probability from the occurrence of the profit state in the next round.
[0055]
Further, the probability control means 37 may be used in combination with the case where the profit state re-generation means 33 does not issue a re-generation command, or may limit the re-generation of the profit state in the high probability state by a predetermined number of rounds. good.
[0056]
Further, the probability control means 37 is configured to use a plurality of special aspects of the second symbol display means 16 so as to change the probability when a part of the special aspects of the plurality of special aspects is changed. The type of the predetermined mode of the means 13 and the type of the special mode of the second symbol display means 16 are used in combination, and the probability is changed from the normal probability to the high probability in each round on condition that the game ball in the specific area 24 is detected. When the round ends, the probability may be changed from the high probability to the normal probability.
[0057]
As described above, each embodiment of the present invention has been exemplified, but the present invention is not limited thereto. For example, in the embodiment, the first symbol display means 13 is configured to change symbols on condition that the first symbol starting means 14 detects a game ball. However, the third symbol starting means and the third symbol displaying means for displaying one or a plurality of third symbols are provided in the game area 12, and the first symbol starting means 14 of opening and closing winning type is provided. The first symbol starting means is provided on condition that the third symbol of the third symbol displaying means fluctuates for a predetermined time on condition that the symbol starting means detects a game ball, and the third symbol after the fluctuation is stopped in a constant mode. 14 may be configured to be open for a predetermined time so that the first symbol starting means 14 can easily win a game ball.
[0058]
The profit state generated by the profit state generating means 29 may be a game state in which the player can enjoy some profit, and is not necessarily limited to the example in the embodiment. That is, the profit state generating means 29 sets a plurality of (for example, 18) opening and closing operations of the variable winning means 15 as a unit operation, and among the plurality of special aspects of the stop symbol of the second symbol display means 16, for example, an even symbol In the special mode, a profit state for one unit operation is generated, and when the stop symbol is a special mode of an odd symbol, a profit state for two or three unit operations is generated at an appropriate time interval. Depending on the type of the special symbol display means 16, a function of opening and closing the variable winning means 15 by one unit operation or a plurality of unit operations during a profit state may be provided.
[0059]
The variable winning means 15 may have at least the specific area 24 and open and close between an open state which is advantageous to the player and a closed state which is disadvantageous to the player. For example, a means having a pair of left and right opening and closing blades is used. You may.
[0060]
In addition, the occurrence probabilities of the predetermined mode and the special mode in the embodiment are mere examples, and are not limited to the embodiment. The probability may be appropriately determined in the entire configuration of the game content. The second symbol display means 16 may be provided integrally with the first symbol display means 13, or may be provided separately from the first symbol display means 13 and the variable winning means 15.
[0061]
In the embodiment, the speaker 7 is used as the auditory notification means, and the gaming state display lamp 35 is used as the visual notification means, but either one of them may be used. Further, the speaker 7 may be provided at another place, the game state display lamp 35 may be provided at another place, for example, at the frame portion of the front frame 2, the glass door 4, or other game parts. It may be provided.
[0062]
The number of prize balls obtained by the player per prize may be the same for the variable prize means 15 and the normal prize means 17a and 17b, or the number of prize balls on the variable prize means 15 may be changed to the number of prize balls on the normal prize means 17a and 17b. It may be larger than the number of prize balls. The random number control may be adopted for the variation control of either the first symbol or the second symbol.
[0063]
In addition, as long as the ball game machine has a function of paying out prize balls by winning game balls to the winning means 15, 17a, 17b, it can be similarly executed in a pachinko machine, an arranged ball machine, a sparrow ball game machine and the like. It is.
